Summary on Grant Application Form |
|
The main goal of this programme is to optimise the performance of porous silicon light emitting devices by making them more energy efficient and able to emit narrow-band light in useful beam shape. This will be achieved by structuring devices on the scale of the optical wavelength so that light is forced to interact more usefully with the porous silicon. In order to produce the final devices a complete model of light propagation and emission in porous silicon microstructure devices will be constructed. The benefits of producing efficient porous silicon would be far reaching as porous silicon devices will be more easily interchangeable with the existing silicon chip technology than products in alternate materials. The work is being performed in collaboration with DRA Malvern, who will supply samples to designs provided from Bath. The programme will culminate in the investigation of a novel plano-concentric micro-cavity device using nested onion skin layers of porous silicon to form a hemispherical high-reflectivity Bragg mirror.
